						<h2>About OpenText</h2>
						<p>The <b>Open Geometry Textbook</b> project attempts to design and
implement a web-based platform for acquiring geometric knowledge to form
textbooks via the collective intelligence of a massive number of web users
(or netizens including geometry experts, teachers, learners, and amateurs). An <b>open textbook</b> is a running software system that appears as an electronic, dynamic textbook and is freely accessible. Netizens are allowed to revise the contents of the textbook and can review the latest
revisions and assess them using implemented mechanisms. When the assessments
of revisions are justified, the textbook is updated automatically in real time and
its new version is then published online. Compared with collaborative platforms like Wikipedia and Connexions, domain knowledge collected in the open textbook will be formalized, more focused, and better structured, so software tools can be developed or
integrated to automate the process of theorem proving, diagram generation,
consistency and soundness checking, textbook version maintenance, etc. and thus assist to validate contributions.</p> 
						<p>
The project is initiated in March 2012 at the State Key Laboratory of Software Development Environment of <a href="http://ev.buaa.edu.cn/">Beihang University</a> in China. We are currently in the process of building up an infrastructure for 
the web-based platform and adapting our research methodologies, results, and tools developed in <a href="http://geo.cc4cm.org/">Geo* project</a> to the open textbook to manage knowledge contents and to assist authors to
make sound revisions, as well as readers to assess contributions. A detailed plan for the project can be found <a href="project/timeline.html">here</a>.
</p>
<h2>Objectives</h2>
<p>The main objective of the Open Geometry Textbook project is to design and
implement a web-based platform for acquiring geometric knowledge to form
a textbook via the collective intelligence of a massive number of web users
and to study the feasibility of our open textbook approach for automated acquisition of knowledge
in mathematics, with geometry as a special case. The project will also help
build up a collection of geometric knowledge from netizens' contributions and
an integrated environment with sophisticated software tools for interested users
to access, explore, communicate, disseminate, and publish geometric knowledge. Cuurent research and development focus on the
following three aspects.</p>
